Filing ITR? Here's what AIS and Form 26AS tell the income tax department about you

As taxpayers prepare to file their Income-tax Return for Assessment Year 2026-27, one of the most important steps is to review the Annual Information Statement (AIS) and Form 26AS. These statements are no longer mere tax credit documents; they have become key information tools through which the Income-tax Department captures and analyses a taxpayer's financial footprint during the year.

In recent years, the tax administration has moved towards a data-driven compliance framework. Information reported by employers, banks, mutual fund houses, stock exchanges, property registrars and other reporting entities is captured and reflected in AIS and Form 26AS. Therefore, these statements reveal far more than just tax deducted at source; they provide a broader picture of income, investments, spending patterns, asset transactions and tax compliance behaviour.

What is Form 26AS?

Form 26AS is a consolidated tax statement linked to a taxpayer's PAN. It primarily helps taxpayers verify tax credits available to them for a particular financial year. It reflects details such as tax deducted at source, tax collected at source, advance tax paid, self-assessment tax paid and refunds issued by the Income-tax Department.


If an employer has deducted TDS from salary, or a bank has deducted TDS on fixed deposit interest, the corresponding credit should generally appear in Form 26AS. If the credit is missing or incorrectly reported, the taxpayer may face difficulty in claiming the correct tax credit while filing the return.

What is Annual Information Statement (AIS)?

The Annual Information Statement is a much broader information statement. It provides a consolidated view of various financial transactions and income details reported against a taxpayer's PAN.

AIS may include details relating to salary income, interest income, dividend income, securities and mutual fund transactions, purchase and sale of immovable property, foreign remittances, tax payments, TDS, TCS, capital gains-related information, rent receipts, high-value transactions and other information reported by third-party entities.

What do AIS and Form 26AS reveal about your finances?

Together, AIS and Form 26AS can reveal a wide range of information about a taxpayer's financial profile. Some of the key financial transactions and tax-related details, as provided by Form 26AS and AIS, are as follows:

Income sources

AIS and Form 26AS help identify the different sources from which a taxpayer has earned income during the year. Apart from salary income, they may reflect interest from savings accounts and fixed deposits, dividend income, rental income, capital gains-related information and other receipts reported by third parties. For salaried taxpayers, this is particularly important because income other than salary is often missed while filing returns.

Investment activity

AIS gives a fairly detailed view of investment-related transactions such as transactions in listed shares, mutual funds, bonds and other securities may be reflected based on information reported by depositories, stock exchanges, mutual funds or other reporting entities.

For investors, AIS acts as an important reminder to compute and disclose capital gains correctly. It also helps identify cases where securities were sold during the year but the corresponding capital gains or losses were not considered while preparing the return.

Interest and dividend earnings

AIS may reflect interest credited by banks and financial institutions, including savings bank interest, fixed deposit interest and recurring deposit interest. Similarly, dividend income reported by companies and mutual funds may also appear in AIS.

Property-related transactions

AIS may capture information relating to the purchase or sale of immovable property, depending on the reporting made by registrars or other reporting entities. Such transactions are significant because they may have capital gains implications, TDS implications or may require disclosure of the source of funds.

Foreign remittances and certain high-value transactions

AIS may also reflect foreign remittances, tax collected at source and other specified financial transactions. This is relevant for taxpayers who have remitted funds abroad for education, travel, investment, maintenance of relatives or other purposes.

Such transactions may not always be taxable by themselves, but they help the department understand the taxpayer's financial behaviour and cash-flow profile. Therefore, taxpayers should ensure that the income disclosed in the ITR correlates and supports the financial transactions reflected in AIS, wherever relevant.

Tax deducted, tax collected and taxes paid

Form 26AS continues to be important for verifying tax credits. It reveals the amount of tax deducted at source, tax collected at source, advance tax paid, self-assessment tax paid and refunds issued.

This helps taxpayers confirm whether the tax deducted by employers, banks, tenants, purchasers or other deductors has actually been reported against their PAN. If the tax credit is missing or incorrectly reported, the taxpayer may face a mismatch at the time of return processing, resulting in a lower refund or additional tax demand.

What should taxpayers do if AIS and Form 26AS contains incorrect information?

AIS is based on information reported by third parties and, therefore, may sometimes contain errors or duplication. A transaction may be incorrectly reported, duplicated, mapped to the wrong PAN or reflected at an incorrect value.

Where a taxpayer finds an incorrect entry, they should verify the source of the information and submit appropriate feedback through the AIS facility on the income-tax portal. The taxpayer should also preserve supporting documents such as bank statements, contract notes, Form 16, Form 16A, interest certificates, property documents or confirmations from the reporting entity.
In case of any discrepancy in Form 26AS, taxpayers should verify the details with their own records and approach the relevant deductor/ collector, bank or reporting entity for correction. The ITR should be filed only after reconciling such information with Form 26AS, AIS and the taxpayer's actual records.

Conclusion

AIS and Form 26AS have become essential checkpoints in the ITR filing process for AY 2026-27. While Form 26AS helps verify tax credits, AIS provides a wider view of the taxpayer's financial transactions and income information available with the Income-tax Department.

Before filing the return, taxpayers should carefully review both statements, reconcile them with their own records and ensure that all taxable income has been correctly disclosed. A timely review can help avoid mismatches, reduce the risk of notices and ensure smoother processing of the income-tax return. It is notable that from Tax Year 2026-27, Form 26AS and the Annual Information Statement (AIS) have been consolidated into a new, unified document called Form 168.
